실험 절차

The title compound was prepared from 5,6-dichloro-3-(2-thenoyl)-4-azaoxindole (Example 6B) according to the procedure of Example 2C, using 5,6-dichloro-3-(2-thenoyl)-4-azaoxindole (194 mg, 0.62 mmol), N-chlorosulfonyl isocyanate (81 L, 0.93 mmol) acetonitrile (10 mL), and a temperature of 50° C. The crude N-chlorosulfonyl carboxamide was hydrolysed by stirring in DMSO in a flask open to the air. After dilution with water, the solid was collected by filtration and recrystallized from acetic acid. Yield: 129 mg (58%).
